NUT-LOCK.

. SPECIFICATION forming part of Letters Patent No. 576,037, datedJanuaryv 26, 189'?.

Application led November l2, 1896. Serial No. 611,833. (No model.)l

To all whom,` it may concern:

Be it known that I, CLIFFORD C. CUYLEE,

of Arago, in the county of Coos and State of Oregon, have inventedcertain new and useful Improvements in Nut-Locks; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use it, reference being had to t-he accompanyingdrawings, which form part of this specification.

My invention relates to improvements in nut-locks, and it pertains tothe nut-locks having a specifically-formed key adapted to be passedthrough the nuts just at one side of the thread and when turned toengage the threads on the bolts and thus lock the nut against beingdetached until the key is again turned to release the bolt-threads.

The object of my invention is to provide a nut-lock in which the nut isprovided with an opening extending through the nut transverse thethreaded opening and just at one side thereof, the key-opening extendingpartially into the thread-opening, and to construct the key with a ilatportion enablin git to be turned to allow the passage of the bolt, butwhen turned to bring the round part of the key against the thread itwill engage the thread, thus Wedging it and preventing the removal ofthe nut, and to provide it at one end with a iin, projection, or featherwhich moves in a slit communicating with the keyopening, whereby thekey, when inserted in the nut, is guided in the proper position topermit the free passage of the bolt through the threaded opening of thenut, but when turned around will cause the round portion of the key toengage the thread and also the iin or projection to form a lock toprevent the removal of the key until it is turned to bring the fin in aline with the said slit.

In the accompanying drawings, Figure l is a perspective view of a nut,showing my invention applied thereto. Fig. 2 is a sectional view of thenut, taken longitudinal of the key. Fig. 3 is a perspective view of thenut, showing the key turned in a loekedpositon. Fig. 4 is a detachedperspective view of the key.

Referring now to the drawings, A indicates an ordinary nut provided withthe usual central threaded opening B`- The nut may be of any desiredform without departing from or affectingin any manner the spirit of myinvention. A key-opening D is formed through the nut transverse thethread-opening just at one sidethereof, but passing slightly through thethreaded opening, as shown at d. Also formed in the nut, longitudinalthe key-opening at the side thereof opposite the threadopening in thenut, is the longitudinal slit b, the function of which will be presentlyset forth.

The key G- has the central body portion c and at one end a head d',which may be angular, as here shown, or of any other form by means ofwhich the key may be readily turned after it is inserted in itspassage-Way or opening in the nut. The opposite end of the key isprovided with a iin or projection e, adapted to engage the slit in thenut when the key is being placed in positions for use. Intermediate theends of the key it is cut away, as shown at j', sufficiently to'leavethe threaded opening B of the nut free and uninterrupted by the key whenit is in position in the nut. Attention is called to the fact that thisflat or cut-away portion f is at the opposite side of the body portionof the key from the fin or projection, so that when the key is placed inthe nut and forced endwise through its receiving-opening the flat orcut-away portion will be adjacent the threaded opening of the nut topermit of thefree passage of the bolt therethrough without anyinterruption or impediment. lAttention is also called to the fact 'thatthe cut-away portion is a distance from the head of the key equal to thedistance from the outside of the nut to a vertical or central line drawnthrough the nut, so that when the head of the key is made to engage theside of the nut the flat or cut-away portion is opposite or adjacent tothe threaded opening B of the nut.

From this description it will be seen that in placing the key inposition in the nut the flat portion is caught to the right position topermit the free passage of the bolt therethrough. The nut having beenplaced upon the bolt a turn of the key will cause the round portionthereof to engage the threaded part of the bolt, as Will be readilyunderstood, and thus lock the nut in position thereon.

The fm. or projection on the end ofthe key IOO is a distance from thehead oi' the key equal to the width ordiameter, as the case may be, ofthe nut, so that after the key is placed in position with the headagainst the side of the nut the turning of the key will cause its roundportion to engage the thread of the nut and at the same time turn theiin or projection at the opposite end of the key to one side of theslit, so that the key is then locked in its passage-way against removal,as will be readily understood, without first turning it to bring the finor projection in line with the said slit. lVhen in that position, it maybe readily removed, as will be readily understood.

From the above description it will be seen that I produce a simplenut-lock consisting of a key which, when turned, performs the doublefunction of locking the nut in position and of locking the key itself inposition against removal.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. Anut-lockcomprisingthenuthavingthe usual threaded opening, a keypassage-way extending through the nut transverse the threaded openingand passing through one side of the threaded opening and communicatingtherewith, of a key adapted to pass through the said key-opening andhaving at one end a iin, and intermediate its ends a cutaway portion adistance from the head equal to the distance from the outside of the nutto a central line drawn through the nut transverse the key,substantially as and for the purpose described.

2. A nut-lock comprising a nut having the usual threaded opening, akey-opening extending transverse a threaded opening and communicatingtherewith, a slit extending throughout the length the key-opening and atone side of the threadedopening, and a key having an intermediatecut-away portion for the purpose described, and a tin or projection atone end adapted to register with the said slit, substantially asdescribed.

3. A nut-lock comprising a nut having the usual threaded opening, akeyopening extending transversely the threaded opening and communicatingtherewith, a slit eXtending longitudinal the key-opening, a key havingan intermediate cut-away portion, at one end a head and at the oppositeend a rin or projection adapted to engage the slit, the iin being adistance from the head equal to the width of the nut, whereby theturning of the key will lock the nut in position and also the keyagainst removal, substantially as described.

In testimony whereof I afiix my si gnature in presence of two witnesses.
